Got this LT1 that spun a bearing from over revving, he had this motor in his RX7 then rebuilt it. It was bored over .30 and ported and polished. New pistons, new crank, but we think it's the same rods. Since I don't have the tools needed to do the swap, a friend of mine is doing the swap. I was told today one of the pistons were backwards... This kid that sold me the motor is suppose to be an experienced mechanic. When I say kid I mean 20-21 years old. He says he's rebuilt plenty of motors before and he seemed legit at the time. Other problem my friend says is it's extremely hard to turn the motor over. It's suppose to be tough, but not that tough. I'm not much for the internals of motors, but is this motor worth trying to put in after fixing these problems or should I find this guy and get my money back? But it was for a pretty damn good price, I would like to put the motor in if it's at all possible. I'm willing to bet it's not going to be as easy as getting my money back and giving his motor back. I'm not going to call him either about the problems with the motor, were going to take it by a machine shop and get opinions from someone there too. I'll call him up one day with the list of problems when I'm ready if it comes down to it.

I'm a little lost on why its hard to spin over and you can physically see the pistons.
There's a lot fishy w/ your purchase though. Normally when you spin a bearing or do any bottom end damage you need to change everything, including rods, they are cheap(stock style)

But, If its together its going to be hard to turn over if its got plugs in it. w/o plugs you should be able to put a regular length 1/2" drive ratchet on the crank and spin it.

Just how cheap is cheap?

The heads are off, along with the oil pan, and valve covers. It's 400 cheap.
